                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 The evening looked promising, but when I was up in the dome doing my
 checkout I noted rain to our N/NW and W in the basin.  I decided to keep
 things closed.  Around 21:15 I could see a pretty good lightning show
 (with rain) now to our West with radar indicating it (slowly) heading
 this way (a little too iffy to try and open).   We were under clouods
 around 22:00 and the rain started around 23:00.  It was a localized
 system but a very slow moving one.  Thick clouds lingered overhead the
 remainder of the night and we never opened.
 I called the night at 04:05 due to increasing clouds again.

     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
